Radiofrequency Ablation for Pain and the Future of Precision Pain Care
Radiofrequency Ablation for Pain and the Future of Precision Pain Care
By: Dr Timothy Ko
As a board-certified, fellowship-trained pain medicine physician, I routinely meet patients whose lives have been narrowed by chronic pain. Despite physical therapy, medications, and lifestyle changes, many continue to struggle—or experience side effects that limit long-term treatment options. These challenges have accelerated the evolution of radiofrequency ablation (RFA), a minimally invasive procedure designed to treat pain at its source.
What Is Radiofrequency Ablation?
Radiofrequency ablation is an outpatient procedure that uses controlled radiofrequency energy to disrupt pain signals carried by specific nerves. Rather than masking pain with medication, RFA directly targets the nerves responsible for transmitting pain to the brain. When used in appropriately selected patients, this approach can provide long lasting pain relief while preserving surrounding structures and function.
How RFA Works: The Science Behind Pain Relief
Pain signals travel from injured or irritated areas of the body to the brain through small nerves. These nerves act like electrical wires, carrying signals that tell the brain, “This hurts.”
Radiofrequency ablation works by using gentle heat to interrupt those pain signals. During the procedure, a small probe is placed next to the nerve that is causing pain. The heat changes how that nerve sends messages, so fewer pain signals reach the brain.
This treatment does not remove the nerve or damage nearby muscles or tissues. Instead, it focuses only on the pain-carrying part of the nerve. Over time, the nerve may slowly regain the ability to send pain signals, which is why pain relief can last for months but is not always permanent.
Using live imaging during the procedure helps the physician place the probe exactly where it needs to be. This precision is important—it improves results and helps keep the procedure safe¹.
Conditions Commonly Treated With RFA
RFA has demonstrated benefit in a range of chronic pain conditions, including:
- Chronic neck and low back pain due to arthritis
- Sacroiliac joint dysfunction
- Knee osteoarthritis
- Pain from peripheral neuropathy
- Certain cancer-related pain syndromes
Importantly, most evidence-based treatment protocols require diagnostic nerve blocks before proceeding—an approach that helps improve patient selection and avoids unnecessary procedures².
Safety and Patient Selection
When performed by trained specialists following established guidelines, RFA has a strong safety profile. Most patients experience only mild post-procedural soreness and return to normal activity within days. RFA is a highly targeted therapy with an impressive safety profile even in sensitive anatomy due to the use of live x-ray guidance and proper sterile technique means infections are very rare. RFA is a low-risk procedure for most patients, but careful examination of patients for known risk factors is important to avoid complications³.
Innovation and the Future of RFA
The field of interventional pain medicine continues to advance rapidly. Emerging technologies such as neuro-navigation, robotic probe placement, and regenerative-hybrid approaches aim to further enhance precision and durability of relief. These innovations reinforce a broader shift toward non-opioid, function-focused pain care.
Precision Pain Care With Purpose
Radiofrequency ablation is not a cure for every pain condition—but for the right patient, it can be transformative. By targeting pain at its source, RFA allows many patients to move better, reduce reliance on medications, and reclaim daily function. A comprehensive evaluation with a pain specialist is the first step in determining whether this precision-based therapy is appropriate.
